Re: Declarative Exception handling question

[Hubert Rabago]

Just to clarify for archive searchers.

The  and  work with declarative
programming.  These tags were introduced to provide the programmer more
control over the formatting of the messages, compared to what 
provide.  For example,  require HTML tags to be present in the
message itself in the application resources file.  With logic:messagesPresent
and html:messages, all the actual formatting can be done on the JSP.  The
example I showed was written just to illustrate the difference between the
regular "validation errors" as opposed to non-validation errors which one
might want to format differently.

Re: Declarative Exception handling question

Thanks Hubert. If you see my last post, you'll see that I solved the 
problem without having to write any Java code -- I did it all 
declaratively and with tags. Nowhere in my code do I create 
ActionMessages instances -- I am trying to let Struts do this for me, 
and stick with declarative programming!

Perhaps people will have opinions on these two ways of solving the same 
problem.

Re: Declarative Exception handling question

[Erik Weber]

OK I solved the problem. The problem was that the html:errors tag that 
is pulling messages from the default bundle apparently renders 
errors.header and error.footer if *any* error message is stored as a 
request attribute, no matter what bundle that error message might come 
from. This seems wrong to me. It seems that if you specify the bundle to 
the html:errors tag, it should only present anything if there is a 
message to display that is from that particular bundle.

So, I had this originally:


The idea was that the top tag would present any form validation error 
messages, while the bottom tag would present any messages associated 
with exceptions that occur after validation has succeeded, such as an 
InvalidLoginException, or similar. The two bundles have different values 
for errors.header and errors.footer, so that the two types of feedback 
can be formatted differently.

But this did not work because the first tag was presenting its header 
and footer even though there were no form validation error messages, 
seemingly because there was an error message associated with the 
exception available as a request attribute. Shouldn't the html:errrors 
tag go a step further, and only render anything if there are messages 
*from the specified bundle* in scope, and not just any error message at 
all? I tried explicity declaring the default bundle in the first tag; it 
made no difference.

Anyway, I enumerated the request parameters present when a form 
validation error occurred, and those present when an exception occurred 
after form validation had succeeded. There was, Thank God because it's 
late, one difference: When an Exception is thrown, there is one 
additional request attribute under the key 
"org.apache.struts.action.EXCEPTION". That request attribute is not 
there when a form validation error has cut processing short.

So then I found the logic:present and logic:notPresent tags . . . . Now 
I have this:







Now, if a form validation error occurs, the top html:errors tag renders 
nothing (this works even without the logic:present tag, but I included 
it for goodness), and the bottom html:errors tag presents the form 
validation error messages, including header and footer, from the default 
bundle. If, on the other hand, an Exception occurs after form validation 
has succeeded, the top html:errors tag renders the exception message, 
with a different header and footer, and the bottom html:errors tag 
renders nothing (event though it so desperately WANTS to), because it 
has been foiled by the logic:notPresent tag.

Someone slap me. The ordeal seemingly is finished.
This also brings up another question: Is there any way to tell the 
Validator plugin to pull messages from some bundle other than the 
default bundle? Ultimately I want my solution to look like this:



The top tag should only render if there are messages in scope *from the 
specified bundle*. Ditto for the second tag. This also would assume that 
the Validator plugin could be told to pull its messages from the 
FORM_VALIDATION_ERROR_MESSAGES properties file, instead of the default file.

Thanks and good night!

Hi,



In regular HTML checkbox, the value of the checkbox can practically be
anything. Does the struts html:checkbox limit us to just yes/true/on
values?

If I have a list of records that I get from the database and I want to
display it with a checkbox at the left, the value of the checkbox being
the id of the record, how do I do that? Should there be another hidden
field for the checkbox with the actual value? And how do I connect the
checkbox to its corresponding hidden field?



I have searched high and low and found no clear explanation. I just want
someone to explain this to me.



Also how does the multibox fall into the picture? Can I use checkbox and
multibox interchangeably?

Thanks

Re: Declarative Exception handling question

[Hubert Rabago]

For validation errors, do the usual, using the saveErrors to pass them to the
JSP:

// validation error
ActionMessages actionMessages = new ActionMessages();
actionMessages.add(ActionMessages.GLOBAL_MESSAGE, 
new ActionMessage("illegal.username", username));
saveErrors(request, actionMessages);


For other messages you want special formatting, save it in a different
request attribute, say "autherrors":

// special error
ActionMessages actionMessages = new ActionMessages();
actionMessages.add(ActionMessages.GLOBAL_MESSAGE, 
new ActionMessage("auth.failed", someOptionalParam));
request.setAttribute("autherrors", actionMessages);

The attribute name "autherrors" is what you'll use to render it differently.

Now, in your JSP, use the  tag to display all the messages
under the "autherrors" request attribute.  If you want to add special headers
and footers, use the  to make sure they don't get
shown when there are no messages.

IMHO, the saveToken(request) IS CALLED for sure. It's actually the opposite,
the token is saved, but never "resest"  anywhere.

A simple "refresh" problem is becoming more and more complicated,
perhaps a uniqueness check on user ID upon creation is the easiest way to
to avoid duplicate records.

Thanks for all of your help, anyway.

RE: How to extract columnNames values

[Indra Gunawan]

I have found a class in Spring framework ... BeanWrapperImpl which is useful
but we have to use it in condition : we have to include Pojo always in ql
 for example we can't query only column names like userid, username 
we have to do it using Pojo itself like Person, User. Then we pass the Pojo
to BeanWrapperImpl which functions as the decorator to make us view the Pojo
as property bag... the rest is easy.

But well, I will check if Hibernate version is more useful. Thanks for your
suggestion David!!!

I believe you want the latest verion of Hibernate which has some Metadata
available which should have the column names.  I've never used it so you

Dear Hibernate Users,

I want to write a component or hopefully find one if there is any that can

using resultset metadata (jdbc brute force way) . And I want to use
Hibernate to do the same .

But the difficulty is Hibernate uses POJO classes . Then one thing came up :
reflection ... but I tend to not using it as reflection will consume

Re: Declarative Exception handling question

[Erik Weber]

Well, this didn't work, the header and footer from the default bundle 
are rendered even though there are no form validation errors, despite 
that the displayed error message is from the other bundle! Perhaps the 
errors.header and errors.footer are "inherited" from the default bundle 
if they are not defined in the secondary bundle?

Regardless, I am back to square one. I would appreciate any help.

popup with dynamic controls

[Christina Siena]

I'm developing a complex UI and need some help with managing dynamic controls in a 
popup.

There is a main screen and a popup.

The main screen displays data in table format:

- in column one, a checkbox so the user can select which row they want to operate on
- in column two, a date range i.e. from 01-01-2005 to 03-31-2005

On the main form, there is a button that the user would select to display the popup.

On the popup, the existing date range is displayed as read-only text as follows:

Existing values:

|min_|max_|
|_01-01-2005_|_03-31-2005_| (this is the value from the selected item on the main 
screen)

Also on the popup, there are two rows of min and max fields as follows:

New values:

|min_|max_|
||| (row 1)
||| (row 2)

The user may enter data as follows:

New values:

|min_|max_|
|_01-01-2005_|_02-15-2005_| (row 1)
|_02-16-2005_|_03-31-2005_| (row 2)

There is a button named "Add More". If the user selects "Add More", the popup should 
display:

Existing values:

|min_|max_|
|_01-01-2005_|_03-31-2005_| (this is the value from the selected item on the main 
screen)

New values:

|min_|max_|
|_01-01-2005_|_02-15-2005_| (row 1)
|_02-16-2005_|_03-31-2005_| (row 2)
||| (row 3)

The user may select "Add More" multiple times to dynamically grow the min-max value 
pairs.

There is a button named "Save". If the user selects "Save", some validation occurs to 
ensure that the min-max date ranges are valid.

If valid, the main form will be redrawn based on the saved data.

I have a few questions about how this should be done:

Can I use JavaScript or do I have to go back to the server to re-display the popup 
with the added row? i.e. the min and max controls

If I have to go back to the server, I only have to go back to re-display the popup 
only, not the main screen, right? I think I answered this myself -- if going back to 
the server, this is the sequence when the user selects "Add More":
(1) close popup passing back to main screen the indicator indicating that "Add More" 
was selected and another indicator indicating that the popup needs to be opened again
(2) submit action with hidden field indicating that "Add More" was selected
(3) in the action, add a row to the map (list) representing the rows (the map is in 
the form bean)
(4) re-display the popup based on the contents of the map (list)
(5) then when the user enters values and selects "Save", the map-backed form 
attributes will be updated (have not tried but it should work, right?)

Now that I've thought about it, I don't think JavaScript is an option to accomplish 
this. Has anyone done something similar? I need some advice about some best practices 
if anyone has developed similar pages.

To further complicate things, these min-max date range entry fields will most likely 
utilize a calendar component, so I need to ensure that I can build that dynamically as 
well (since each calendar has to reference the control). Further, the validation at 
save time also needs to be dynamically generated or I have to go back to the server to 
validate.

If anyone has developed similar dynamically generated pages, any advice would be 
appreciated.

Thanks in advance.

Declarative Exception handling question

[Erik Weber]

I am using the Validator plugin to do my form validation, and so with 
the  tag placed at the top of my content area, the form 
validation messages are presented, with the header and footer defined by 
errors.header and errors.footer. In the traditional manner, the form 
validation output looks something like this:

Error
Please correct these errors:
* Username is required
* Password2 must match Password1
Now, I am also presenting non-validation error messages in the same 
location on some pages; These are caused by Exceptions that are 
accounted for declaratively in struts-config.xml. The problem is, I 
don't want these messages to be presented with the header and footer (or 
maybe I want a different header and footer).

A concrete example:
For my login page, if you fail to enter a username or password, I want 
the error message presentation to look like the example above -- with a 
header and a footer (causing a table with a bulleted list to be 
rendered). But, if you enter the *wrong* password, and an 
AuthenticationException is thrown, the user ends up back at the same 
screen, except this time, I want the error message to be unadorned (or 
possibly with a different treatment), like this:

Authentication failed
As I said, AuthenticationException is handled declaratively. What is the 
easiest way to present the message associated with the exception 
*without* the header and footer in this case, while leaving the form 
validation error presentation (with header and footer) intact?

No, you can have anything you want as the value.  It might default to yes or
true, I haven't tried it.

Use the 'value' attribute of the  tag, then if the box is
checked, that value will be submitted as the value of the form element.

(Checkboxes are special-- only successful/checked ones will be submitted, so
read the docs and reset them properly or you'll never be able to UNcheck
them.)

> Also how does the multibox fall into the picture? Can I use checkbox and
> multibox interchangeably?

No... checkbox is a single thing, and corresponds to a String property in
your Form bean.  Multibox corresponds to a String[], because you can choose
more than one item.  Here's an example of multibox:


   
 



Technically, I suppose you could use multibox in place of checkbox, but if
you're expecting multiple values, checkbox won't work, you'll only ever see
the final value that the browser submitted.

Can html:checkbox take only yes/true/on as value?

[Prashanthi . Pokala]

Hi, 

 

In regular HTML checkbox, the value of the checkbox can practically be 
anything. Does the struts html:checkbox limit us to just yes/true/on 
values? 

If I have a list of records that I get from the database and I want to 
display it with a checkbox at the left, the value of the checkbox being 
the id of the record, how do I do that? Should there be another hidden 
field for the checkbox with the actual value? And how do I connect the 
checkbox to its corresponding hidden field? 

 

I have searched high and low and found no clear explanation. I just want 
someone to explain this to me. 

 

Also how does the multibox fall into the picture? Can I use checkbox and 
multibox interchangeably? 

Thanks

Prashanthi

Pardon the obvious, but just in case you're WEB-INF should be:
/home/virtual/sitexyz/fst/var/www/html/WEB-INF/struts-config.xml

If that's it again, pardon the obvious, but how is the struts-config.xml coded in 
the web.xml?

  Tomcat is running with Apache web server, but in a Red hat linux

  Hi,
I've been developing a struts webapp using tomcat and am now trying to

I'm using Tomcat 4.1.29 in the development machine and Tomcat 4.0.3 in

I wonder if this problem might have to be with the way  is

- server.xml -

and this is the way my hosting company configured it for me:

Can you provide a bit more information and code?  What do you have for 
global forwards in your struts-config.xml?  Where is the "welcome" 
forward called?  Etc.

this is the associated .jsp:

It seems  the "welcome" global forward isn't being found in

When calling an action directly I get a "Not Found" error. I'm beginning

What do you think might be the problem?

The nested map is what proves interesting, as I think you have to drop to a scriptlet

Please HELP with HARD problem: STRUTS-tags VS Proxy, Weblogic loadbalancing, and BASE tag

[Lukas Latz]

Hi List,

I'm badly stuck with a STRUTS web-app that runs fine on Tomcat, but refuses
to bahave nicely in production, where a Netscape Proxy on port 80 maps to a
Netscape Webserver on port 8080, which in turn, with Weblogic plugin, does
loadbalancing to 2 Weblogic machines on port 7001.

As I don't have a lot of STRUTS experience, I stuck closely to the
struts-blank application and tuto, and used the struts-html tags as
advertised, including the  tag and the  tag.

Accessed through the proxy, the RequestUtils.getActionMappingURL() that (it
appears) does the real work inside those tags produces wrong servername /
port combinations (correct would be the Proxy's name on port 80).

What compounds the problem is that the web-app is a frameset.
Unusual, granted, but works just fine in Tomcat (inter-frame communication
with event-model using javascript).

The wrong resolution of  leads to multiple user-sessions within
the frameset (Bad Thing) (one session per frame).

Without success, we've tried several strategies to get around the problem:

- use  or just the regular html  tag, hard setting server
to proper value -> still gets multiple sessions, also can't get the port
right.

- get rid of  tag in all incarnations, only use relative links from /
level, works just fine on tomcat but still fails in production, presumably
because the  tag still resolves wrong?
.. could also be because I still use RequestUtils.getActionMappingURL() to
get the URL for the frame src definitions in the frameset. I had trouble
getting the frames any other way in the absence of the base tag.


I'm now wondering if I can safely do completely without RequestUtils and use
simple html  instead of struts  ??

Does the core functionality of Actions, ActionForms and mappings still work
if I replace the struts  tag with just  ??

Or is there another way around this?

Any pointers much appreciated !

Lukas

Using the standard JSP tags, we can pretty do much do anything on a page, e.g.:
<%
List list = new TreeList();
list.add("first");
list.add("second");
Iterator iter1 = list.iterator();
while(iter2.hasNext()) {

Filters, listeners and struts-config.xml

[Jim Barrows]

I've just googled to see how to get a filter to grab info from struts-config.xml, and 
haven't been able to find anything on it.  I had assumed  that it would have been a 
nice idea to have a StrutsFilter, just to be able to access the global forwards.
Have I missed something? Is this a 1.2 feature?
Should I invent this wheel?

The real problem is that your combination of server technologies 
(proxies plus webserver plus servlet container) is not maintaining the 
original URL from the browser all the way through to the servlet -- its 
being modified along the way.  Thus, you are going to have problems with 
*any* technology based on the servlet API (not just Struts), because 
such applications will always assume that they can reconstruct request 
URLs in the way that Struts does it.  Indeed, the assumptions that 
RequestUtils makes are based on *requirements* in the servlet 
specfication that your combination of technologies are, unfortunately, 
violating.

That's not a problem that Struts can fix :-(.

Of course, you can bind a validation to an action mapping using the 
ValidatorActionForm -- however this still forces your business 
objects to extend this form and it doesn't solve the populate problem.

Well, I'm actually not talking about binding the validation to a 
"form" or any bean but binding it to a mapping. The framework then 
will look at the basic request parameters and validate them based on 
some configuration for the mapping and of course return back to the 
user any errors. It never gets to the population of the bean (POJO/VO 
whatever) until after validation succeeds. Of course you could still 
get an ugly conversion error there if you don't validate properly but 
that's the case with any system. At least with the above approach you 
aren't tied to having to rely on an ActionForm simply for validation 
purposes.

As far as the problem of migrating deeply nested VOs to Action Forms 
-- we have the same issues on the app that I am working on -- I feel 
your pain ;)

Yea, annoying - especially if you have to validate stuff that is nested:)
The key thing to remember is that in Struts, ActionForm is part of the 
*view* tier, not part of the *model*.  It only exists to provide Struts 
a place to store the server side representation of the input data in 
your fields.

Validation was one of the motivations for this design, but not the key 
one.  The primary motivation was to meet a user expectation that, when 
they make a mistake, the form will be redisplayed with exactly what they 
typed into the field, even if it was wrong.  For example, if you have an 
integer field, and I type "1a3" instead of "123", I expect to see an 
error message and what I originally typed (1a3) there for me to fix.  
This is the reason you need string fields -- that's where Struts puts 
the originally typed value, so it can be redisplayed.

JSF does indeed avoid the need for an ActionForm like structure, because 
all the state saving and conversion logic is buried inside the component 
itself.  If you use a value binding expression to tie the value of the 
component directly to a model bean property, you don't even have to 
worry about defining what conversion to use; the binding machinery will 
take care of it for you.

With JSF, I see three different idioms for hooking input fields to data 
objects becoming popular, depending on your background and preferences:

* Bind component values to model bean properties,
 and have event handlers in separate classes
 (since conversion errors are handled for you, the model
 bean can use native data types).
* Bind component values to backing bean properties, and have
 the corresponding event handlers in the same class (sort of
 an ActionForm + Action combined, similar to what WebWorks
 does).
* Instead of binding component values to bean properties,
 bind components themselves (using the "binding" attribute),
 which makes it easy to programmatically modify component
 properties (similar to what ASP.Net does if you use
 code behind pages).
All three models are reasonable, and are not mutually exclusive within 
the same application.

This suggests that either your Action is not being called (the form is being
cached by the browser or the server), or you missed the call to
saveToken(request).

I actually do this a lot.  Struts doesn't have support for adding parameters
to redirect at runtime, but a lot of people add the support right in.  I have
extensions which allow you to add not just parameters, but also ActionMessage
objects so you can pass arguments as well as messages like "Your changes have
been saved".  See http://www.rabago.net/struts/redirect  

Admittedly it seems like a lot of work to add it into an existing project. 
That's because of the ActionMessage support.  If you don't think you're going
to need ActionMessage support but still want something for passing arguments,
download the first patch attached to bug 866 (which is for this very issue):

Yes, the problem is that even if the form is regenerated, it is STILL USING
THE SAME REQUEST object, which means that the token still stays there.

Well, since we need to pass argument to the index page after user creation, 
so redirect doesn't seem to be possible

Not sure haven't looked at JSF yet:) Plan to at some point. Craig?
Of course, you can bind a validation to an action mapping using the 
ValidatorActionForm -- however this still forces your business objects 
to extend this form and it doesn't solve the populate problem.
Well, I'm actually not talking about binding the validation to a "form" 
or any bean but binding it to a mapping. The framework then will look at 
the basic request parameters and validate them based on some 
configuration for the mapping and of course return back to the user any 
errors. It never gets to the population of the bean (POJO/VO whatever) 
until after validation succeeds. Of course you could still get an ugly 
conversion error there if you don't validate properly but that's the 
case with any system. At least with the above approach you aren't tied 
to having to rely on an ActionForm simply for validation purposes.

As far as the problem of migrating deeply nested VOs to Action Forms -- 
we have the same issues on the app that I am working on -- I feel your 
pain ;)
Yea, annoying - especially if you have to validate stuff that is nested:)

RE: Initialization stuff

[Martin I. Levi]

Yeah, but I just need to do initialization when the application starts,
the validator and tiles are working all the time when requests come and
go. Perhaps is a good solution also, but is mine wrong or discouraged?
Thats what i really would like to know.

Although I often use servlets for initialization, Paul's suggestion is 
better because ServletContextListener was designed exactly for 
initialization/finalization purposes.

Using the right tool for the job is a good practice even if you gain 
nothing more in functionality; it makes your application 
components/logic easier to identify later.

So i guess I should refactor too ;-)

Re: Check for forward

Create a custom RequestProcessor that extends the Struts 
RequestProcessor. In the custom class override the processForwardConfig 
method to do whatever you want.

True, as Michael also suggests (WEB-INF is by default protected by the

So I guess my question should be rephrased as "looking for something in

I think a  much cleaner approach would be to bind a "valdiation" to your

an ActionForm).

I think Struts ties your hands too much forcing reliance on the use of 
ActionForms for everything. For your typical simple JSP form, 
ActionForms are not that big of a deal (although I still find them a bit 
annoying), but it really falls apart when you have to create some 
complex forms where you have a lot of nested objects. It's incredibly 
annoying trying to convert all the nested objects, sometimes in our 
case, three or four deep, into nested ActionForms. You're probably going 
"ughh" what kind of form is that:) but business requirments dictate we 
need it since we're stuck with the initial objects coming back as VOs.

multiple struts-config.xml and validator.xml files for dealing with "stories"

C)  [Conventional class] is NOT used, data form validation is defined within the

I've had deep discussions with other large teams in similar circumstances, and the 
consensus has been that (C) is the most safe, sane, and simple route.
I would also recommend finely-grained DynaValidatorForms to ensure only the expected properties are captured and validated. 

Nowadays, I also use finely-grained Struts configs, so that each "pageflow" or "story" is represented by its own struts-config.xml and validator.xml. This requires a strong naming convention to be sure the members of each config overlaps, but it makes it very easy to work with each use-case or story independently. 

 

Do you have an example which uses multiple struts-config.xml  and 
validator.xml files for dealing with "stories"?

logic:iterate fails on (large) collection

consensus has been that (C) is the most safe, sane, and simple route.
I would also recommend finely-grained DynaValidatorForms to ensure only the expected properties are captured and validated. 

Nowadays, I also use finely-grained Struts configs, so that each "pageflow" or "story" is represented by its own struts-config.xml and validator.xml. This requires a strong naming convention to be sure the members of each config overlaps, but it makes it very easy to work with each use-case or story independently. 

So instead of allocating a module or multiple struts-config to a "team" or "component", we 
allocate them to each use-case or story. You do end up with lots and lots of struts-configs, but if they are 
well-named and use strong conventions, finding what you need is actually faster and easier than pouring through 
several much larger files. You can see the trees within the forest. There also tends to be less "cruft" 
since each struts-config is cohesive and only contains the elements used by a given story.
(I discovered finely-grained struts-configs as part of a spelunking session. I pulled out all 
the elements for a pageflow to figure out how it worked, and then realized this was a pretty 
cool way to handle struts-configs in general. My team calls it "config-behind-story".)
The business rules validations are often better handled by a non-Struts component that can be used outside of Struts or shared by Struts applications. This validation can take place after the Action executes. The trick is to have the business-rules validator return messages that can be converted to Struts Action Messages. If we ever finish the migration to Commons Resources, this part will be cleaner. We may also see more uses of Commons Validator outside of web application frameworks. 

You might also want to look at Niall's extension  
which could work itself into the distribution one day if LazyDynaClass is accepted by Commons 
BeanUtils .

We are having an internal discussion about the best
use of struts for a large heavy-input data-driven web application.
We have discerned 4 approaches in the way we can use Struts. Given
this example class:
Class (form bean)
Public class Person extends  implements java.io.Serializable {
protected String firstName; protected String lastName; protected
int wein = 0; }
These are four types of Struts usage:
A)  Person extends ActionForm, and provides implementation for
validate() method - validate data form and data type enforcement,
and then validates some object level business rules before handing
off to Action class

B)  Person extends ValidatorForm, and provides implementation for
validate() method - validate data form through against
validation.xml through struts, and then validate some object level
business rules before handing off to Action class.

C)  Person is NOT used, data form validation is defined within the
validation.xml and handled by struts, the Action class (or some
surrogate) then enforces all business rules.
  
 
D)  Person is a business object only implementing
java.io.Serializable with no knowledge of application space, data
form validation is defined within validation.xml handled by struts,
the Action class then enforces all business rules.
  
I personally prefer C. It is my understanding that DynaActionForm
should be used as a "firewall" to collect all strings (to return
invalid data to the client), use the Validator to perform
client/server side validation, the Action then copies the form data
into business objects, and then invokes delegates to perform
business processing.
Please feel free to be candid with your views. I appreciate your
time reading this.
Thanks,

RE: Initialization stuff

[Paul McCulloch]

You can do this by creating a class which implements
javax.servlet.ServletContextListener.

This requires a container supporting Servlet 2.3.

Perhaps you can write a Plugin

that is the way how tiles and Validator gets init.

Initialization stuff

[Martin I. Levi]

Hi!

I would like to call an initialization class when my web application is
loaded in the container to perform some extra init tasks. How should I
do this?
My idea was to subclass the ActionServlet and override the init method,
is this ok or is there a better way to do this?

Any help is welcome.

Thanks!

Declarative Exception Handling

[Ashutosh Satyam]

Hi All,
 If I'm going by the Declarative Exception handling approach,
either by configuring  in the struts-config.xml file
or by using the exception element of , how do I replace

property file.

Kindly provide some insight into it.

Validator confusion

[nikhil walvekar]

Hi,all

in class 
org.apache.commons.validator.Field
There are two member fields.
indexedProperty
protected java.lang.String indexedProperty

-
indexedListProperty
protected java.lang.String indexedListProperty


Please tell me differnce between the two.

In validation we user indexedListProperty then for which purpose indexedProperty is 
used and how?

Please HELP with HARD problem: STRUTS-tags VS Proxy, Weblogic loadbalancing, and BASE tag

[Lukas Latz]

Hi List,

Sent this yesterday, but it seemed to not get through to the list. My
apologies if it's come through already. :

I'm badly stuck with a STRUTS web-app that runs fine on Tomcat, but refuses
to bahave nicely in production, where a Netscape Proxy on port 80 maps to a
Netscape Webserver on port 8080, which in turn, with Weblogic plugin, does
loadbalancing to 2 Weblogic machines on port 7001.

As I don't have a lot of STRUTS experience, I stuck closely to the
struts-blank application and tuto, and used the struts-html tags as
advertised, including the  tag and the  tag.

Accessed through the proxy, the RequestUtils.getActionMappingURL() that (it
appears) does the real work inside those tags produces wrong servername /
port combinations (correct would be the Proxy's name on port 80).

What compounds the problem is that the web-app is a frameset.
Unusual, granted, but works just fine in Tomcat (inter-frame communication
with event-model using javascript).

The wrong resolution of  leads to multiple user-sessions within
the frameset (Bad Thing) (one session per frame).

Without success, we've tried several strategies to get around the problem:

- use  or just the regular html  tag, hard setting server
to proper value -> still gets multiple sessions, also can't get the port
right.

- get rid of  tag in all incarnations, only use relative links from /
level, works just fine on tomcat but still fails in production, presumably
because the  tag still resolves wrong?
.. could also be because I still use RequestUtils.getActionMappingURL() to
get the URL for the frame src definitions in the frameset. I had trouble
getting the frames any other way in the absence of the base tag.


I'm now wondering if I can safely do completely without RequestUtils and use
simple html  instead of struts  ??

Does the core functionality of Actions, ActionForms and mappings still work
if I replace the struts  tag with just  ??

Or is there another way around this?

Any pointers much appreciated !

Lukas
